You're on a roll — here are the corrections for your work. Question 2 2.1 What is the phenotype of: a) Homozygous recessive The homozygous recessive genotype is bb. Since 'b' controls white fur, the phenotype is white fur*. Answer: White fur b) Rabbit Y Rabbit Y has genotype Bb. Since 'B' (black fur) is dominant over 'b' (white fur), the phenotype is black fur*. Answer: Black fur 2.2 Give the NUMBER only (X, Y or Z) of the rabbit that is/are: a) Homozygous Homozygous means having two identical alleles (BB or bb). Rabbit X is BB (homozygous dominant). Rabbit Z is bb (homozygous recessive). Answer: X and Z b) Homozygous dominant Homozygous dominant means having two dominant alleles (BB). Rabbit X is BB. Answer: X 2.3 Represent a genetic cross to show the possible phenotypes and genotypes if rabbit X and Y would mate. Parental genotypes (P): Rabbit X (BB) × Rabbit Y (Bb) Gametes from X: B, B Gametes from Y: B, b Punnett Square: |c|c|c| Gametes & B & b \\ B & BB & Bb \\ B & BB & Bb \\ Possible Genotypes (F1): BB (50%) Bb (50%) Genotypic ratio: 1 BB : 1 Bb Possible Phenotypes (F1): All offspring will have at least one dominant 'B' allele. Therefore, all offspring will have black fur*. Phenotypic ratio: 100\% Black fur Send me the next one 📸
